Performance Face-Off
Suction Power
The Dyson V7 excels in suction power, particularly on carpets. Its direct-drive cleaner head digs deep into carpet fibers, effectively removing embedded dirt and pet hair. The Dyson V7 maintains consistent suction throughout the cleaning process, ensuring thorough performance on various surfaces.
The Shark IONFlex also provides strong suction, but its DuoClean technology is designed to balance suction with brushroll action. The two brushrolls work together to capture both large and small particles on hard floors and carpets. While it may not have the same raw suction power as the Dyson V7 on carpets, the IONFlex’s brushroll system is highly effective at surface cleaning.
Hard Floor Cleaning
The Shark IONFlex shines on hard floors thanks to its DuoClean technology. The soft brushroll gently polishes the floor while capturing fine dust and debris, leaving a clean and streak-free finish. The strong suction ensures that larger particles are also effectively removed, making it an excellent choice for homes with hardwood, tile, or laminate flooring.
The Dyson V7 performs well on hard floors, but its single brushroll may not be as gentle as the Shark IONFlex’s soft brushroll.

However, with the right attachments, the Dyson V7 can still provide a satisfactory cleaning performance on hard floors.
Carpet Cleaning
The Dyson V7 is particularly strong on carpets due to its direct-drive cleaner head. The stiff bristles agitate carpet fibers, loosening embedded dirt and pet hair for effective removal. The powerful suction ensures that the debris is lifted and captured, leaving carpets clean and refreshed.

Pet Hair Removal
The Dyson V7 is a top choice for pet owners due to its powerful suction and specialized tools. The mini motorized tool is particularly effective at removing pet hair from upholstery and carpets. The strong suction ensures that even deeply embedded pet hair is lifted and captured, leaving surfaces clean and hair-free.
The Shark IONFlex also performs well in pet hair removal, thanks to its self-cleaning brushroll. This feature reduces hair wrap, ensuring consistent performance and minimizing maintenance. While it may not have the same raw suction power as the Dyson V7, the IONFlex’s brushroll system is effective at capturing pet hair from various surfaces.
